Abstract: UNITAP and UNIWRI are programs to read and write
(respectively) various kinds of "foreign" magtapes
on a RSTS/E system. Both are preset to default to 800
bpi, IBM SL tapes, fixed records, EBCDIC character code.
The following characteristics may be selected by the
user, if the default is inappropriate: 800/1600 bpi;
EBCDIC/ASCII/BCD character codes; with or without tape
labels; fixed or variable blocks; LRECL and block-size.
 
Both programs support wild-carding. UNITAP also supports
the following features: dump only the first N records on
the tape; dump a random N% sample of the records on the
tape; invoke a user-supplied function to
modify/select/reject each record; print a directory of
the tape (with no output to disk).
 
. Both programs also compile and run under BASIC-PLUS-2,
  for faster execution and/or large block-sizes.
 
. HELP messages in the programs and comments in the source
  code.
 
The following improvements have been made:  Some error
traps were fixed, a few new character codes have been
added to the XLate table, a few inconsistencies were
corrected.
